While building latest git tree I see several 'funny' errors. LD kernel/built-in.obfin-linux-uclibc-ld: Warning: size of symbol `_sys_futex' changed from 4 in kernel/sys_ni.o to 262 in kernel/futex.obfin-linux-uclibc-ld: Warning: size of symbol `_sys_set_robust_list' changed from 4 in kernel/sys_ni.o to 30 in kernel/futex.obfin-linux-uclibc-ld: Warning: size of symbol `_sys_get_robust_list' changed from 4 in kernel/sys_ni.o to 170 in kernel/futex.obfin-linux-uclibc-ld: Warning: size of symbol `_sys_setfsgid16' changed from 4 in kernel/sys_ni.o to 16 in kernel/uid16.obfin-linux-uclibc-ld: Warning: size of symbol `_sys_setfsuid16' changed from 4 in kernel/sys_ni.o to 16 in kernel/uid16.obfin-linux-uclibc-ld: Warning: size of symbol `_sys_setresgid16' changed from 4 in kernel/sys_ni.o to 36 in kernel/uid16.obfin-linux-uclibc-ld: Warning: size of symbol `_sys_setresuid16' changed from 4 in kernel/sys_ni.o to 36 in kernel/uid16.obfin-linux-uclibc-ld: Warning: size of symbol `_sys_setuid16' changed from 4 in kernel/sys_ni.o to 16 in kernel/uid16.obfin-linux-uclibc-ld: Warning: size of symbol `_sys_setreuid16' changed from 4 in kernel/sys_ni.o to 26 in kernel/uid16.o...

and later:

LD .tmp_vmlinux1bfin-linux-uclibc-ld: Warning: size of symbol `_sys_mremap' changed from 4 in kernel/built-in.o to 82 in mm/built-in.obfin-linux-uclibc-ld: Warning: size of symbol `_sys_ioprio_set' changed from 4 in kernel/built-in.o to 362 in fs/built-in.obfin-linux-uclibc-ld: Warning: size of symbol `_sys_epoll_wait' changed from 4 in kernel/built-in.o to 1002 in fs/built-in.obfin-linux-uclibc-ld: Warning: size of symbol `_sys_timerfd' changed from 4 in kernel/built-in.o to 346 in fs/built-in.obfin-linux-uclibc-ld: Warning: size of symbol `_sys_ioprio_get' changed from 4 in kernel/built-in.o to 344 in fs/built-in.o

I did not look into these. I assume it is a toolchain issue??

PS. I had to fix a few things to get so far but as I did not doit the right way I have no patch.
